为什么Opencart没有将变量从模块传递到查看文件?

问题描述

我是opencart的新手.默认情况下，Opencart特色产品显示产品说明和价格，但是现在我希望特色产品部分有产品折扣价，所以我更改了特色产品代码并添加了代码以显示折扣价.这是特色产品的完整代码

I am new to the opencart.By default Opencart featured product shows product description and price but now I want product discounted prices in featured product section so I changed my featured product code and added code to show discount price. Here is the complete code for featured product

<?php
class ControllerModuleFeatured extends Controller {
  protected function index($setting) {
    $this->language->load('module/featured'); 
    $this->data['heading_title'] = $this->language->get('heading_title');
    $this->data['button_cart'] = $this->language->get('button_cart');
    $this->data['text_discount'] = $this->language->get('text_discount');
    $this->load->model('catalog/product'); 

    $this->load->model('tool/image');

    $this->data['products'] = array();

    $products = explode(',', $this->config->get('featured_product'));    

    if (empty($setting['limit'])) {
      $setting['limit'] = 5;
    }

    $products = array_slice($products, 0, (int)$setting['limit']);

    foreach ($products as $product_id) {
      $product_info = $this->model_catalog_product->getProduct($product_id);
      $discounts = $this->model_catalog_product->getProductDiscounts($product_id);
      $product_discounts[] = array(); 
      foreach ($discounts as $discount) {
      $product_discounts[] = array(
        'quantity' => $discount['quantity'],
        'price'    => $this->currency->format($this->tax->calculate($discount['price'], $product_info['tax_class_id'], $this->config->get('config_tax')))
    );
      }

      if ($product_info) {
        if ($product_info['image']) {
          $image = $this->model_tool_image->resize($product_info['image'], $setting['image_width'], $setting['image_height']);
        } else {
          $image = false;
        }

        if (($this->config->get('config_customer_price') && $this->customer->isLogged()) || !$this->config->get('config_customer_price')) {
          $price = $this->currency->format($this->tax->calculate($product_info['price'], $product_info['tax_class_id'], $this->config->get('config_tax')));
        } else {
          $price = false;
        }

        if ((float)$product_info['special']) {
          $special = $this->currency->format($this->tax->calculate($product_info['special'], $product_info['tax_class_id'], $this->config->get('config_tax')));
        } else {
          $special = false;
        }

        if ($this->config->get('config_review_status')) {
          $rating = $product_info['rating'];
        } else {
          $rating = false;
        }


        $this->data['products'][] = array(
          'product_id' => $product_info['product_id'],
          'thumb'      => $image,
          'name'       => $product_info['name'],
          'description'=> $product_info['description'],
          'price'      => $price,
          'special'    => $special,
          'rating'     => $rating,
          'reviews'    => sprintf($this->language->get('text_reviews'), (int)$product_info['reviews']),
          'href'       => $this->url->link('product/product', 'product_id=' . $product_info['product_id']),
          'discounts'  => $product_discounts,
        );
      }

    }
    if (file_exists(DIR_TEMPLATE . $this->config->get('config_template') . '/template/module/featured.tpl')) {
      $this->template = $this->config->get('config_template') . '/template/module/featured.tpl';
    } else {
      $this->template = 'default/template/module/featured.tpl';
    }

    $this->render();
  }
}
?>

现在，当我使用

 <?php foreach ($discounts as $discount) { ?>
  <span class="discount-price">
     <?php echo sprintf($text_discount, $discount['quantity'], $discount['price']); ?>
  </span>
  <?php } ?>

它显示未定义的变量$discounts.但是，如果我在模块文件中使用print_r($discounts)，则在那里显示折扣价.我真的很坚持这一点.为什么模块没有将值传递给视图文件?有人可以帮我弄这个吗?任何帮助和建议都将是可贵的.

It is showing undefined variable $discounts. But if I am using print_r($discounts) in module file it is showing the discount price there. I am really stuck with this. Why the module is not passing the value to the view file? Can some one help me with this? Any help and suggestions will be appreciable.

推荐答案

您应该在foreach中使用$product['discounts']而不是$discounts

You should be using $product['discounts'] not $discounts in the foreach
